In coastal British Columbia, mild climates and infrequent disturbance favour
the development of long-lived forests with trees of great stature. These
forests are admired the world over for the magnificent ...

A three year study of lakes and stream of southern Victoria Land was conducted from 1983-1986. In the first season, the algal composition and physico-chemical characteristics of South Victoria Land ...

This research attempts to determine the role - CO2 source or sink - of the
Southern Ocean on a regional and seasonal scale by implementing an
integrated multidisciplinary approach which combines in ...

In English:
This project is aimed to achieve a higher knowledge of the limnetic systems in
Polar latitudes. Particularly, it promotes the accurate description the Byers
Peninsula (Livingston Island), ...

This is the largest isotope foodweb study ever attempted in a marsh ecosystem, and combines detailed, long-term, trophic and biogeochemical studies at selected well-monitored USGS/SFWMD/FGFFC sites ...

Microbes with the nitrogenase enzyme on mosses and soils, particularly the cyanobacteria Nostoc, were examined to investigate the extent and magnitude of the nitrogen fixation process. Sample cores ...

The purpose of "Availability of Organic Carbon for
Denitrification of Nitrate in Subsoils and Groundwaters" is to
determine the amounts of organic carbon and nitrate in subsoils
and groundwaters from ...

The purpose of "Below Ground Responses to Global Environmental
Change and the Biogeochemical Dynamics of Carbon" is to provide
new insights into the effects of expected environmental change
on ecological ...

Ice core records provide highly detailed records of how different components of the climate system have behaved in the past. DRAM will make use of these and other data to pin down the main forcings ...

This data set provides 3-hourly estimates of gross ecosystem CO2 exchange (GEE) and respiration (autotrophic and heterotrophic) for the state of Alaska from 2012 to 2014. The data were generated using ...

Data are available for four atmospheric trace gases at nine stationary
sites and one moving platform (aircraft over Cape Grim, Tasmania, and
Bass Strait, between the Australian continent and Tasmania). ...

(Adapted from an Abstract Presented at ARS Carbon Storage Workshop)
"Missing" carbon has been identified publicly as a major problem in
balancing the annual global carbon budget for at least 22 years. ...

The objective of the "Carbon Sequestration by Switchgrass
Managed as an Energy Crop" dataset is to monitor carbon
sequestration over time in switchgrass and to compare the
economic and carbon sequestration ...

Salps are planktonic grazers that have a life history, feeding biology and population dynamic strikingly different from krill, copepods or other crustacean zooplankton. Salps can occur in very dense ...

Land-Margin Ecosystem Research in the Columbia
River Estuarine Turbidity Maximum (CRETM) is an
interdisciplinary approach to investigating
couplings between hydrological, geochemical and
ecological ...

Ocean food webs modify the efficiency with which CO2 is absorbed from the atmosphere into the sea, fixed by phytoplankton in the surface layers and then transported to the ocean interior. This so-called ...

The "Denitrifying Activity in Deep Soil Profiles" dataset
contains data on what factors control denitrifying activity in
deep soil profiles. Its purpose is to evaluate an N-based method
for measuring ...

Ecological investigations into the waters of the Darwin Glacier region (extreme southern end member to the Dry Valley system) were carried out to extend knowledge of microbial processes to high latitude ...

The purpose of "Effects of Global Climate Change on Carbon
Cycling in Peatlands" is to evaluate the effects of global
change on carbon balance in peatlands and on gaseous exchanges
of carbon between ...

The purpose of "Effects of Nutrient Transport in Cropping
Systems in Environmental Quality and Fertilizer Efficiency" is
to assess dynamic nitrogen (N) transport in high-residue
conservation-tilled ...
